If you are using Linux, try:

1. try using command lppasswd to create user and password (it is called CUPS digest pw file) which you can use for http://localhost:631
I use root and its pw.
2. Try to make all cups files permission to lp lp first and then tighten it and test as you require.

NAME
lppasswd - add, change, or delete digest passwords.
SYNOPSIS
lppasswd [ -a ] [ -g groupname ] [ -x ] [ username ]
DESCRIPTION
lppasswd adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt for the old and new passwords. When run by the super-user, lppasswd can add new accounts (-a username), change existing accounts (username), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames, but only UNIX usernames are supported by the CUPS client programs (lp(1), lpr(1), etc.)

The -g option specifies a group other than the system group - "sys", "system", or "root", depending on the operating system.
